Valhalla

Valhalla could be seen right after you open the gates to Asgard. It has 540 wide doors and the roof is made of golden shields. Every morning warriors of Valhalla would go out to fight battles and return to Valhalla, it doesn't matter if any limbs were missing because at the end of the day they all will be restored.

Valkyries
In a mortal battle, Valkyries decides who lives and who dies in battle, they send dead warriors to Valhalla. They are female hosts and they ride on flying horses. They like to hover in the clouds above and watch a war and then judge.
