Nicely done Gryph!! Very nicely done, indeed!And I too suffered from major breakage, first from the "All these worlds" message, then as the realisation started sinking in about where they landed. Right up until the mention of "First Lensman" I was going no... no way. Ive gotta be wrong... HOLY COW! I'm Right!
Loved all the things that others have mentioned, and do put me down as yet another voice who hopes that the DDP's from this story get an occasional cameo in other UF stories.
