Scratch explanation: When the sessions' ectobiologist create the players' and guardians' paradox clones, they're sent through Skaia's portals on meteors heading towards earth (Ludus in this instance). When the scratch happens, Skaia's portals change so that the meteors arrive on earth  (Ludus in this instance) at different times, switching the roles of the players and the guardians. In the beta session, RDB and Ivan and Taku and Stickbeard and Sanford and friends were the players while LD/ZX/HGD/DMS/LAT/S17/Laz/PS were their guardians (Or, in some cases, ancestors) while in the alpha session it went vice versa.

(Just for anyone who didn't know.)
