Liche is derived from some foreign speak word for corpse, I think

I think that's more akin to a draugar.

A lich transforms his body into an undead husk while hes still alive, and keeps his soul in a reliquary.
If his body is ever destroyed, then a new body is created near the reliquary.
If the reliquary is destroyed, then the lich is killed.

liches aint shit but hoes and tricks

Yeah, it's a word the vikings brought to England that means corpse.

There's an old English town with the word, called Lichfield founded in the 7th century, with an interesting local legend you could check out.

A lich is typically a powerful mage, who in order to combat his own mortality, has delved into the forbidden arts of necromancy. Thus, he binds his soul to a suitable vessel, a phylactery, while his body is transformed by the necromantic powers. Everyone that follows Death in life can find no peace when it comes to claim their souls.

They have no problems with keeping a huge amount of undead servants to do their bidding and act as defenders of his blasted lair.
