Loyxo was an assistant representative from the Guild, sent to Arrakis in 10,194 AG, with his leader, Ertun, and fellow assistant Crozeed, to request of the Emperor Paul Atreides, an increase of the allotment of melange to their organization. Loyxo, like many members of the Guild, had human anomalies to his anatomy; in particular, he had an extremely thin face, which bore scars of reconstruction.
