Allies

Saloroc (Orcs)

The orcs we have met (near Freeport) were fighting against, and fleeing from, the evil that drove the goblins. The Red Skull clan acted with honour, and came to the defence of a human village that was raided. They probably don't like Falcor much, though...

Since then we have learned much of the Saloroc Clans:

Tiger Clan

The former ruling class of the Orc Clans, they are honourable and intelligent, worship Korman but seek an independent, free and civilised Orc Nation.

Dragon Clan

Haven't been seen for centuries are thought by many to be the stuff of myth and legend. The stories tell of highly intelligent Orcs who served the Dragon King with honour. Said to have produced many powerful mages.

Red Skull

Stayed true to Korman and are good allies to the party, fortifying positions around the Temple of Light and Custor's tower. Proud sailors and warriors with Shamans supporting them.

NOT ALLIES - Listed here for completeness:

Black Hand Clan

The new rulers, but turned to darkness by the Snake clan and the influence of the lizard folk, worshiping Kraldar.

Snake Clan

Worshipers of Kraldar, and allied to the lizard folk (who worship Kraldar as a creator), they seem to be behind the takeover of the Saloroc nations by the Black Hand and Red Hand clans. Seem to be a (dark) priestly order.

Red Hand Clan

Foot soldiers that support the Black Hand - not clear if they also worship Kraldar or are just willing to follow the strongest Clan that take a leadership role.

Wolf Clan

Xenophobic, highly organised and excellent warriors. They don't worship any deity and live largely separate from the other clans. They supported the Black Hand and Snake clans in overthrowing the Tigers but then withdrew again.

Custor

The Watcher, tasked with awaiting the return of "He" - the king of the Elvradrak - and teaching him in the ways of magic. The last of an order that has passed the task down through the ages. Human who might dabble in necromancy and creature control.
