Obsidian is an earth genasi sired by a summoned dao and his sorcerress human mother. He was born on Radole, his mother exiled to the planet and left to die for her crimes. His father keep both mother and son alive but not lift a hand to rescue them as obsidian's mother had hoped when she had summoned the dao.

Years passed and he had a few adventures on Radole. It was at this time he learned his fighting skills from an exiled adventurer named Ula. His last adventure on Radole was an encounter with the dragonfly ship sundancer as it landed in the hot zones of Radole looking for motten metals that lay near its surface, hoping to get some precious metals from skimming it surface (they had specially treated equipment for such 'mining'). It is here when Obsidian's spelljamming adventures started. From the start, Obsidian's attitude almost got him stranded on Radole even before the ship took off into wildspace (He is known for one of his 'endearing' remarks "Kiss my ..."). He found that he liked being a marine aboard the sundancer. While he has proven to be a valuable marine, it seems trouble follows Obsidian wherever he travels.

While visiting a spelljammer port he got into trouble with the law when he started to deface idols and images of gods (in his mind where were the gods when his mother prayed to be spared the fate of being exiled to the lousy planet of Radole). He was arrested and spent some time in prison, after he finished his sentence, the local preisthood quested Obsidian to obtain a prized jewel that was stolen from the temple and return it to the priesthood all in one piece and not shoved down the throat of any priest or clergy member (actually it was worded very carefully so Obsidian could not find a way to twist the quest).

How to Fit Obsidian into your spelljamming campaign Characters can come across Obsidian in his quest for the sacred jewel. If they come back to port after losing a lot of crew, the PCs might find it hard to replace lost crew as the marines and sailors in port have come to believe the PCs (or thier ship) is jinxed, Obsidian, being one of the few that is not supersitious, will hire on. Obsidian is expensive to hire as he wants either 50 gp a day or a half share of any booty with additonal payment of 5 gp per day.

Obsidian does not like clerics one bit and will never defend one, nor help them. If in a middle of a bar brawl Obsidian will wade into the fray with fists flying, and if he sees a cleric .... well lets say the cleric will have a few more bruises that day!

As to other character classes, he gets along with bards really well as he enjoys thier songs, healing and boosting of morale. He likes any warrior or fighter-types on board a ship. If women are on board he will be protective of them, especially if they are wizards or sorcerers. And if any woman shows any inclination of showing him love or affection... well there will be hell to pay to those who attack such beauties as Obsidian will go out of his way to punish the 'wicked'.

He does not expect healing from clerics (and will appreciate healing from bards) and as such he uses his alchemy skill to whip up some stinky Healing Salve[T&B] to have ready to cure damage from future battles he may get into. Many adventurers find Obsidian's knowledge of alchemy and herbalism extensive for a marine with no spellcasting ability.

One last thing, if any one really does kiss his posterior, he will respect that person more than those who do not (they have humbled themselves before Obsidian). He does not have any problem kissing any posterior, except that of any priest. Yes, he is arrogant and crude!

When played correctly, most players will love to 'hate' Obsidian for his very crude behavior. Still, Obsidian will not steal from his employer, will be forthcoming about his disdain of clerics, and he will not run from a fight unless the odds are overwhelming or under a magical compulsion (such as a fear spell).
