Well, I've finally stuck some of the materials for my old Star Trek: Challenger campaign up on the web. The material has been ported over to ICON. Much of this material was converted back when I was offering my gaming group a choice between reviving their old ship and exploring the Dyson Sphere in my Star Trek: Relic campaign.
Included is a whole raft of characters originally generated using the FASA rules and a set of rank equivalent tables between the Federation, Romulans, Klingons, Cardassians and Bajorans. The Romulan ranks are based on the LUG Way of D'Era for officers and FASA for enlisted personnel, with Centurions being more closely related to the way the Romans used them than either game. The Cardassian ranks are taken from the Cardassian Netbook. Klingon ranks are the same as on my Star Trek: nomghar campaign page, based on Marc Okrand's The Klingon Dictionary. Bajoran ranks are loosely based on modern Western military ranks, consistent with those seen on DS9.
A full and exhaustive treatment of Starfleet Intelligence Section 31 is given.
