MMORPG Data
There are two unique and different types of monsters within Uthgol: the social monsters and the wandering monsters. Each lives a very different life, with different goals and different threats. However, these two types of monsters also have a number of things in common. Everyone needs to travel Uthgol, exploring Grendel's Realm. Everyone needs to fight Uglies and other monsters. (Or, at least, everyone likes fighting Uglies and other monsters.) Finally, everyone gets better as they travel the realm and use their special abilities.
If you wander around, exploring Grendel's realm, you'll inevitably fight Uglies. These vermin have invested Uthgol like cute little bunnies. So, of course, you must kill them. Most Uglies in Uthgol are "adventurers", which is another name for roaming-mindless-monster-killers-without-honor. You'll see clerics, skilled in both the martial and healing arts; fighters, the most mindless of all the killing machines; magicians, who burn and freeze and shock with magic; and thieves who skulk and attack from hiding. None of them are fit to live in Uthgol under Grendel's shadow. You can fight other monsters too. In particular it should be noted that chimera don't get along that well with undead and undead aren't that found of humanoids and humanoids don't like chimera. And for that matter, humanoids don't like undead too much either ... you get the idea. Wandering monsters tend to be roving sources of death and destruction and are sometimes the target of massed social attack. Clans sometimes also engage in warfare against other clans while fighting for resources or looting lairs.

Grendel's Revenge is a game of roleplaying and achievement.
As a social monster you will be able to form clans and build lairs. You will join together with your fellows in a complex social structure. If you are able you will slowly build your own web of followers until you can break your ties with your own master and form a clan of your own.
