While the Ether inhabits the space between planes, then Limbo can be said to be the time between them. It has an interstitial, static quality to it, conceding liminal movement from one frozen moment to another until arrival the next temporal pocket. Adventurers travelling to the distant past of Shala'jen often find themselves hurtling through Limbo. The nexal Glade of Isolation is nestled in the mists of the plane, as is the bizarre Holding Room. It is upon the plane of Limbo that Lord Twilight, God of Darkness constructed His floating fortress.
Rumour has it that when Limbo seeps upon the planar pathways of Yggdrasil, Memory is born. It is all that was of what lies behind and what lies before.
Exploring Limbo does not affect your ranking within the Fellowship of Explorers.
