The armies of the Thousand Deaths

19500 orcs
18500 goblins (a note: Goblins are the engineers of Kilomor's city (Int 18). Thus, Kilomor uses kobolds to attack places where his other armies can't fit.)
14000 trolls
14750 hobgoblins
11500 ogres (2-headed; 5+2 HD and +2 on surprise rolls)
9750 ogre mages (2-headed; 6+3 HD and +3 on surprise rolls)
16000 gnolls
13500 flinds
20 red abishai and 1 pit fiend (revered by Kilomor and subjects; referred to as �Daemons' and �Daemonlord' (names: Abishai: Deeor, Atruui, Muuhyuppi, Minjurt, Aleato, Gukyr, Yturrt, Kuiyly, Bavuj, Sweqm, Xudlug, Darknis, Isst, Buddu, Ferrtuyl, Yoreutr, Ieyes, Nuit'ra, Judraap, Juytutewurld. Pit fiend: Teleono)
30 age category 8 red dragons
Morsilvanus, an age category 11 legendary (Elder) (Dungeon Master Option: High-level campaigns p. 61-67) shadow dragon
S: 25 D: 15 Co: 24 I: 21 W: 20 Ch: 19 Hp: 341 AC: hit only on rolls of 20s. THAC0: -11
MV: 25 Fl 42 (enhanced movement) Jp 4 Size: 84' 6" Powers: Crush (5d8) Enhanced melee damage (+3/die), Enhanced Movement, Regeneration (2/round) Physical Invulnerability (+2 or better weapon to hit) Alignment: Special. Acts Lawful good towards Kilomar, Lawful Neutral to all other humanoids and Chaotic evil towards everything else, except baatezu, when he acts Lawful evil. A note: Morsilvanus has killed many planar creatures, among them tanar'ri (including balors), aasimon (including solars), eladrin (including tulani), gehreleths (including shators), yugoloths (including ultroloths), guardinals (including leonals), and rilmani (including aurumach), so he has fallen into disfavor with many beings and powers. (Stories tell of aasimon and tanar'ri actually working in tandem to slay Morsilvanus. Upon their defeat, however, they destroyed each other.) Thus, if your PCs are on a quest to defeat The Thousand Deaths or Morsilvanus, there's a chance that they might send aid (the near-omnipotent Morsilvanus won't care one way or another about this, however.)

The size of Kilomor's city (nation is a better word) is overwhelming: 35 million goblinoids occupy it, including the armies and such. The city itself exists on a huge island, with the city itself at the base of a dead volcano, Kilomor's pure onyx palace built about 7 miles up the volcano, and finally the dragon's nests (Morsilvanus tends to take up alot of space).
