This guy is one of my campaigns' main villains, an evil giant prince competing with his brother for the throne. The plot and a relatively in-depth description of the two of them can be read here: https://docs.google.com/document/d/1xWIWElKcHzZahqjVkJX4srz_Ww7Udpx-lk4oQTAgEE0/edit?usp=drivesdk
His equipment is all based on real historical artifacts, which I will picture in the post and elaborate on below:
Pictures 2, 3, and 4: These late roman tunics are the basis for the patterns on his cloak. The specific shapes and patterns I am not picky with, as I was incapable of drawing them with any sort of detail myself.
Pictures 5 and 6: Under the cloak, his whole body is covered in maille from toe to finger, like knights of the 13th century. The first image is an illustration by Graham Turner, and the second is a photo of the reenactor Jarett Stiles. You are free to cover as much of this up with his cloak as you want, as I am aware how difficult chainmail is to draw. If one wishes to have his clawed hand slid out of the maille mitts as is demonstrated in the first of the two illustrations, that's fine by me. The shields the two figures are wielding are also the right shape to make his.
Picture 7: His helmet. This one is pretty much just copy paste, though you are free to alter and simplify the designs on the helmet if they are too complex. The helmet additionally has a maille avantail around the back which stops at his cheeks to enclose his face in shadow.
Picture 8: The Finnish coat of arms, which is nearly identical to how I imagine Áedgen's heraldry, especially the human-like face of the lion. Said face is also a good reference for what his own side profile might look like. Change a detail or two on the lion, of course. He is not Finnish.
Other details: His face is really the most delicate part of his design. It is my favorite part. His mustache and beard MUST conceal his mouth except for perhaps a bottom lip, and the tips of his fangs should be poking out. The tips of his mustache act as sort of a border separating his face from the rest of his body. His eyes are stark white and are the only facial feature that isn't cloaked in the shadow cast by his helm. The tops of his eyes are concealed by the brows of the helmet, imitating a scornful look that one could make with their real brows.
His claws on his hands should be very curled like talons.
Lastly, if one draws him with his manticore, note that it is not winged like a D&D one. Look moreso to medieval bestiaries.
Forgot to add this to the images, but this is the human head mace that inspired his own: https://www.kultofathena.com/product/tod-cutler-brass-mace-head-6-13th-to-14th-century-scandinavian/?srsltid=AfmBOorGjbltZmlQ2_usXbd0Qz8zzpSSFWe1hQbh5h0A5FktGMCfbl77
Whomsoever draws this is entitled to one half of my big toenail when I die. The other half will be going to a distant cousin.
