Sithis appears to be in their late 20's, with black and red hair, inhumanely smooth caramel skin, and unnaturally bright red eyes. You can generally find them in positions close to those in power. With a passive want for control but a hatred for spotlights and attention, you’ll notice a pattern of them working from the shadows and lurking in the corners. Don’t be fooled by their initial appearance, they are very friendly and love cracking jokes with those who wish to have a nice chat with them. They also love gothic and alternative fashion as well produced a method of glamouring their horns, hair, scales, and tails at whim. However, with a mysterious past and a tendency not to get too close or personal with others, you may find it takes some time and effort to uncover their true history and meet the more fun loving side of them.
(You cannot know this info in character until Sithis reveals it to you.)
Sithis is a voidsent that feeds on the aether of others, though they only do so when given express permission. They got into Eorzea through a summoning and in a ravenous and starved hunger, consumed all of the summoner’s aether and then moved into the now late summoner’s home. They read a lot of the history and etiquette books left behind by this summoner and adjusted their manner of communication and interactions with the people of Eorzea. Wanting to put this learned knowledge to use, they went to venues frequently, putting their rigorous studies into practice.
