World Tree

This sentient, astral tree connects all of the celestial planes to each other.

From it's roots in Dwarfhome and Arvandor, it's lower branches in Greenfields, the House of the Triad and Dweomerheart and it's higher branches in the House of Knowledge, Golden Hills and Brightwater right to it's top in the very Gates of the Moon themselves. Angelic servants of the good gods use the tree as a kind of 'celestial ladder', avoiding having to go through the Prime Material Plane, although the tree doesn't enjoy being used as such by others. If their intentions are noble enough the tree does allow them to travel up and down it.
