Krolling Sen shipyard was a facility of the Dasklo family situated on the Chiss Ascendancy planet Ornfra. It served as the premier shipyard for the Dasklo, as well as a center of space travel research and development. Captain Clarr'os'culry "Roscu" of the Clarr family visited Ornfra to investigate Krolling Sen on the orders of Patriarch Clarr'ivl'exow "Rivlex," believing that the Dasklo family was involved in a threat against the Clarr due to the manipulations of the Grysk "Jixtus."
