Basso's Companions

Gandalf was considered a bearer of ill news and trouble. He was often regarded as a bringer of woe that would send off many Hobbits on "fool errands." Basso was one such Hobbit that Gandalf most likely enticed to go on an adventure.

With this in mind, the mission and companions could be disputed, but this would have been the most likely list for T.A. 2795:
 * Gandalf
 * Basso
 * Argonui
 * Gildor
