Sverre Kvernmo has an authorship career that began with his Cabal series, split between solo releases and the Master Levels for Doom II, and seemed to end on the first edition of ETERNAL, authoring among other things the enormous, intricate MAP12, "Darkdome". He went full in to game development but never truly left the fold, peeking in every now and then. Sverre returned in 2013 with the visually striking Plasmaplant and at some point began his PAR project. PAR was to be a Doom II megaWAD whose casual 100% completion durations could be accomplished within the original par times as set by John Romero. The restriction must have lost its luster, though, and what was once PAR evolved into Echelon.
