Trollwife

A trollwife is a female troll; despite the name, there is no requirement that she be married (nor, in fact, do trolls normally engage in formal marriages). A typical adult trollwife stands 11 feet tall and weighs 700 pounds. They have no outward appearance of femininity, at least according to the standards of humans or elves; rather, a trollwife simply looks like an extraordinarily large troll. Like a normal male troll, a trollwife has lumpy skin that is a dull grayish green in color.
When encountered, a trollwife may be alone, cohabitating with a male (her "husband"), or raising a brood of trollkin.
Trollwives are solitary with respect to other adult trollwives, for they hate each other with a fierce passion. If forced together they will put aside their enmity until all non-troll enemies are dead (at which point they may well fight over who will eat the choicest of the remains).
