Monument to Lost Explorers

In a reality, the Monument to Lost Explorers was a location in the Capitol. Members of the Watch left wreaths on it. (PROSE: The Infinity Doctors)

Lost explorers were common in early Time Lord history, before TARDISes were perfected. (PROSE: The Chronicles of Doctor Who?) The Eighth Doctor once found the marooned TARDIS of one such explorer. (PROSE: Dead Time)
