From publisher blurb:
This Conversion Guide is an indispensable referee’s companion as Calidar sourcebooks are otherwise system-neutral. It provides all game statistics written for the OSRIC System. This supplement covers the three books in Calidar’s Meryath arc:
CAL1 “In Stranger Skies” Gazetteer
PG1 “Players’ Guide to Meryath”
CA1 “Dreams of Aerie” Adventure
Each of the original books is treated as a separate chapter in this Conversion Guide, exactly in the same order as presented in the source material. Each translated entry shows easy-to-use page references linking back to the source material. This conversion booklet goes a bit further, as it provides game stats that weren't included in CAL1, delving with great detail into the Star Phoenix's crew, the foes, and the monsters.
