 All cultures in the world have legends about a strange being approaching rulers and offering their services. They wear a long purple cloak, and their face is always shrouded in a strange shadow. They call themselves the Royal Advisor Tecarys. They ask only for  a token payment for their services, but they always have a few stipulations. First, nobody is to see what they look like under their cloak. Second, nobody is to enter their room uninvited, no matter what. Third, they require a black goat on every winter solstice to do with as they please. If a ruler agrees to these stipulations, Tecarys will serve them for an undisclosed length of time. The shortest they agreed to remain was three years, and the longest just over a century. However if any of their stipulations are violated, they leave on the spot. According to all available records those rulers that listened to their counsel and stuck to the agreement all left a flourishing and powerful state to their successors, but t...

  Made from a strange type of fabric that's soft yet strong, the Mantle of the Stars is practically humming with magical power. It is a heavy black cloak, lined with melinkar  fur. On its back small magical lights, which may look like especially brilliant gems from afar depict the constellations of the night sky. Whoever puts on the Mantle will be able to see the starts, even in broad daylight. They will also be able to perceive their slow movement across the sky, and even be able to accurately estimate when certain celestial events will be happening. Additionally they will gain the ability to fly, and move items up to the size of a large cow with their minds. Currently the Mantle is in the possession of Nefter-Atla, High Priest of Khepsu , who uses it to predict the annual flood with amazing precision, which has earned him the ear of the Reptilian Pharaoh.

 Made from the bleached skull of some unknown monster, this helmet is enchanted to strike fear into the hearts of enemies. This effect has a deceptively large radius, and can easily turn the tide of battles of the wearer is deployed tactically. For this reason it is highly sought after by both warriors and generals. The helmet itself is an ancient skull of some beast with large canine teeth and ram-like horns mounted on a pretty basic bronze helmet. Two large emeralds are embedded in the skull's eye sockets.  The helmet was last seen in possession of the great human warlord, Edereth. Unfortunately it was never recovered after his death, and it is suspected that it lays with him in his tomb, which nobody has managed to find so far.

 Temples are the dwellings of the gods. This is not just a metaphor, they are constructed according to precise measurements and floorplans to align with the chosen deity's palace in the realms of the gods. The innermost sanctum corresponds to the throneroom of the deity, and houses their statue. What the statue is made of can vary depending on the deity in question and the local availability of materials, but marble, gold, bronze, and ivory are popular choices. If constructed and consecrated properly, the temple will act as a bridge between worlds. Those that enter will not only be in the temple upon the earth, but will simultaneously be in the deity's palace in the divine realm, able to directly converse with the deity, who will be superimposed with their statue. This of course means, that since the temple exists on both the physical and the divine realms, everything that is in the temple is also on the deity's plane of existence, and is henceforth their property. This inc...

 This one-of-a-kind magical spear is special not just because of the powerful enchantment it has, but because it is made entirely of steel - shaft and all. It is engraved with runes both sacred and demonic, and its point has a red tint that no amount of cleaning can get rid of. Otherwise it is almost offensively bare, with no decoration, or seemingly even thought given to its aesthetics. As the name implies, the Demigod-Slaying Spear was forged for one purpose: to kill the offspring of gods, spirits and demons . Its maker, a smith named Nekar-Tash who lost everything in his life save for his forge, bled himself to death over it to empower its enchantment, and the royal sorcerers of Nashat-Ippur, who have studied it closely for four years after the city captured it in battle theorize that its ultimate goal is to kill full-bloodied deities, and that killing demigods is just a means to further empower it in service of that goal. Whatever powers it may unlock in the future, currently t...

 Ruler of the northern forests, and sovereign of all boars, Keranos is a respected deity of Caeledor , even if he isn't amongst the most powerful. According to legend it is he who digs spring out of the ground, and the Sorcerer-Kings of Caeledor trace their families back to him. Besides being the bringer of spring, he is also able to grant unending vitality, and even immortality for a short period. According to Caeledorians the first horn was made from his tusk, so he is also the patron of music and dance. This is reflected in the royal houses of Caeledor, whose singing can magically influence people. They are also supernaturally talented with musical instruments, and some may even be able to heal the sick. The latter ability is actually a requirement for someone to ascend to the throne of Sorcerer-King, as it is believed to be a direct blessing from Keranos.  To his priests Keranos grants the ability to heal, to enchant, and to make things grow. They may also bless warriors t...

  Alternatively known as Stone Sickness, or the Grey Plague, Basilisk plague is a slow-acting disease which gradually turns the infected into stone. The plague spreads by eye contact, and there is a small period of time where the infected don't show symptoms, but are already infectious. The infected are generally encouraged to blind themselves, and in most places are required by law to wear a blindfold at all times. While the plague can spread incredibly quickly, most of the population is actually naturally immune to it, even if this fact is not generally recognized, and the infected are treated as incredibly dangerous, and are usually quarantined into a separate building or district, where only the clergy that try to treat them are allowed. Unfortunately the Basilisk plague shows an unusual resistance to magic, with only the most powerful sorcerers being able to cure it.  Symptoms start with small gravel-like growths on the skin, usually on the arms, legs and neck, which then...
