Arms from vanilla represent 15th c. Hungary.
About Sicile you probably mean these.



The Hauteville dynastic arms. It's one of the two possibilities but they may not have been adopted before 1189 (so it's a more hypothetic choice).

Last one for today. Alternate Lithuania.



Hope I got them right cause I have almost no reference seals for eastern heraldry.

You won't see the claws with the low picture size used by the game. They sometimes are blazonned gold in the rolls but its not very important in medieval heraldry believe me. So yes, it's details :)
