Nah. Even if we read their bios now, it's out of the universe. We can't skip PC communication and assume your PC instantly know each one's other backstories just because you read it.
Besides, not everyone remembers about bios.
If our characters want to know others, they'll have to ask, of course.
I'll post mine here as well.

Lek Itonnanir (Bristle Hallrhyme) was born fifty-six winters ago from a simple family, in the desertic, hot dwarven fortress of Thusestlisat (Furynotches).
His early years as a child were not the most peaceful. Between the numerous sieges which clashed against Thusestlisat's mighty iron walls, the goblin child snatchers, and the random squads of enemy ranged soldiers, it was not stuff.
What he did developed during his early years was his personality. Far less prone to random idiocy like young dwarves, but when he did fall to inexperience it was generally pretty brutal, so much so that he did saw his fair share of hospital beds and two-month-long waits. Most importantly, he never really felt that much attracted by wealth as much as dwarves, and he did developed his battle lust. Far more than any other child and rivaling some of the more intense warriors, in fact.
His first kill was at sixteen. It was another goblin searching for a child. Lek suddenly felt a rush to fight this goblin, and he did indeed followed that rush.
The goblin, surprised at this attack from an unarmed, unarmored civilian dwarf, did not even put any solid resistance as Lek overcame him and quickly downed the goblin, thereafter mashing his skull to a paste.
The event did not go unseen. This, along with Lek's tendency to start fights with other young dwarves for fun, did provided incentive to get Lek into the militia. Lek was subsequently pleased, remembering the great tales of warriors of old that he did enjoyed when he was young.
He also knew the life of the soldier, the endless training sections only stopped by sleep, eating, the rare breaks, and the common siege which one should defend against. These moments were the most intense and pleasuring, far outstripping such trivialities such as a good mug of dwarven ale.
Lek wasn't the strongest, not the fastest, nor the most prone to raise morale with a good speech. Nevertheless, his stoic composure, firm grasp of tactics, watchful eye, sagacity and most importantly his dedication to battle did enough to counter the flaws. Very few could match the enthusiasm of Lek when going to battle. Even the sparring was took just as seriously as the actual fighting, except with less battles to the death.
Then he got bored of militia life, around his fifties, mostly because it was always the same thing, and he got bored of the seemingly endless periods of training... he didn't fought nearly enough for his taste. He wanted to leave, fight other opponents, learn new techniques. He felt that staying here was stagnating as a warrior.
That is why Lek Itonnanir left his native fortress an evening of summer, in his 53rd year. He merely said he was leaving to his family and his squad, and then left. Which was quite a surprise for everyone, because Lek didn't expressed emotions much, mostly because he had not much apart from the desire to do battle, or read more old stories, or study tactics. He did brought nothing but his trusty short sword, a bag of food, quite a lot of water and beer and furs cloth to protect himself from the desert's heat or cold. Not one managed to stop him, nor by force of argument or threats.
While inside the desert, what he thought was his intuition guided him to an old battlefield. It wasn't his intuition : it was Gorum, god of battle and warfare, who was watching him and guided him here.
Here, on the old battlefield, around the discarded swords, armor pieces, wooden standards and old bleached bones, Gorum's avatar manifested from a few old armor pieces.
Lek thought his last hour had come, but no. Gorum, recognizing one who thirsts for war, asked Lek to champion him, in exchange for powers and more battle prowess. Gorum then recited his credo and Lek quickly agreed.
Gorum therefore instructed Lek to go to the closest Gorumite temple, which was alone in a savanna. That he did, and Lek was introduced in the Gorumite faith. He also did exchanged his short sword for a greatsword, and while two-handed was not easy feat for someone used to one-handed sword and shield style, he managed after a few years of training.
Here he learned more about the history of war and tactics, which pleased him greatly. He also developed unarmed combat, mostly with the gauntlet which was mostly an emergency weapon, the dagger which was remarkably similar to the short sword. He also did take up the javelin, mostly to hunt animals and bring food for the cult, as part of his duties. He wasn't very good at throwing, he nevertheless found it a good support weapon to start the battle when he could not yet swing his sword.
He did also know the holy rituals of Gorum and the magic he offered. He was at first reticent, never had really been exposed to magic beforehand, but quickly learned it's value. He could become stronger, heal it's wounds, shield itself, become more accurate... it was perfect for a warrior !
Eight years later, at 62, as a full-on initiated priest of Gorum, and starting to feel the call of the unknown and it's many new, different battles, he was given a holy symbol and he left, to preach the faith of the sword and iron. He did not returned to his childhood's fort, instead going up north for new experiences and new battles.
He then happened upon a fishing village...
