How does it look?

This crude banner looks to be made of some strange leather, but with some strange hues that makes the identification hard. It depicts some runes that seems to be written in dark tongue glyphs, and a red huge boar head, with twisted horns that seems to look with burning red hungry eyes at the world.

There are runes on it.

The meaning of these ancient runes (a dialect of the dark speech) are as follows:

-- The powerful war leader Shagulg the Skinner sacrificed one thousand elves to THE MOTHER long ago. She blessed him with great intelligence and strength for his work.
Shagulg must have been a powerful ogre.
The last lines state that he is the successor of Shaiju.
