Hopefully some Lore buffs on here will have some input on what the do's and don'ts should be.

What you should do is be a bad-ass and beat the living &^%$ out of everything using pretty much absolutely any means necessary whilst outfitted in Orcish armour.

What you shouldn't do is show mercy or weakness.

I guess. No idea. There's no rules.

I have to do that badass dual-wield orc from the loading screen someday (I made an orc, but he was a spellsword).

Enjoy that Berserker Rage. Best power in the game, I think.

i made an orc character as the very 1st 1 for skyrim and used it to be a badass, no mercy-showing, sword and shield warrior... but i just used that char to get myself accustomed to the game and ditched it after a while but a general orcish charismatic generally is to beat up everything and everyone he/she can get his/her hands on

I know right I am really surprised orcs aren't one of the most popular races.
