Vana'diel Bestiary: Stray  

Its incorrect to have on entry for Strays. Although all strays found in Promivyon- Mea, Dem and Holla are wanderer type, in Promivyon-Vahzl they are a different level, and on higher floors weeper and seether type strays are produced from the Memory Recepticle, however they still have the name "Stray." Their attack sets are that of the type of empty their model represents.

These sentries guard the Memory Receptacle, which themselves seal the memory stream which permits travel between the subfloors of Promyvion.

They're nearly identical to the Wanderers both in aggro distance and attack style. Strays are different in that they are generated over time by the Memory Receptacle. If the Memory Receptacle is destroyed and there are still Strays remaining, you must dispose of them before you can enter the memory stream.
