My campaign, A Terror and a Traitor, takes place from 2377 to 2379, if that comes after Derelict. Inferno and The Scroll of Antankharzim after come after Derelict.
My campaign contradicts Inferno on when several borrowed ships appear, though. Here are the ship timelines for T&T (Inferno ships are marked with an asterisk):
GTDn Hades II begins development: 2368
GTD Olemus*: 2369
GTF Valkyrie D.H.* (SOF Banshee in INF): 2372
GTDn Nemesis*: 2373
GTF Hercules Mk III* (GTF Alves in INF): 2373
GTF Phaeton* (SOF Orpheus in INF): 2374
GTB Jotun *: 2375
GTDn Hades II completed (three of them enter service): 2375
GTF Vesuvius*: 2376
Shivans reappear with various INF ships*: 2377
TSF Apollo II: 2376
TSB Kahlan*: 2376
SF/TSF Hydra*: 2376
GTVJ Colossus II: 2376
GTB Jotun D.H.*: 2377
GTB Gagana*: 2377
Ancients appear*: 2377
A story will appear soon, but at the end of T&T, there will be nodes from Barnard's Star to 61 Cygni and from 61 Cygni to Sol, a faction called the Terran-Shivan Alliance (TSA) will be in control of the Barnard's Star, 61 Cygni, and Sol systems (the Sol alliance is defeated at the end of T&T), as well as numerous surrounding systems, the GTVA will be on the verge of collapse, the Ancients will have briefly appeared and then disappeared, but the TSA will be using its technology and ships as well as Shivan and Terran ships and technology, and numerous other things that probably contradict other camapaigns in the same timeframe. Expect a detailed storylne and timeline soon.
Oh wait, did he say PM? Oops. Oh well, it's not like anyone would object to learning more about a new campaign.
