Random Creature Determination

The Creatures encountered depend on which level beneath the surface the player Characters are on.

Roll 1d6 on the table for the player Characters current Underworld Level, then roll again on the indicated Creature Level table.

Number of Wandering Creatures Appearing

If the Underworld level beneath the surface corresponds with the Creature Level Table then there is a single Creature. An exception is that Orcs and the like will be in groups.

A party of more than 3 characters would draw double the number of Creatures.

There can be places where 300 Hobgoblins dwell.

3 Hobgoblins can come abreast down a typical ten foot wide passage.
