Originally the Lynx was a science vessel, it has some items one call weapons, but was purely defense (on coming meteor or other uses). Later as the Grey war occured with the Deletans they were reworked, became about 2 times or more original size. The one used in the last battle with Torin the first was unique and sported technology that even the current Altronians can only rumor to believe might be possible. This made the myth the original Torin might still be alive for centuries long after last embers of the great battle fadded away.
This is a redesign of the great ship buy the new leader of the Altronians, it to seems to be his specialty craft, always with experimental features, weapons, and capabilities.
Anyone who sees one of theses seemingly innocent small craft in the area are wise to not provoke them. It has to date never been known that they have lost any modern skirmish or battle.
Fast, nimble, armored and heavily shielded with defences not possible in larger ships, plus weaponry that rival most battleships or destroyers. Many of their defenses are set to automatic, so even a unassuming sneak attack is not possible. Since the ships own AI often is always on high alert, always scanning...
(In the Traveler Universe Altronians are roughly tech level 30-35, but also way out of the way, rarely seen, and isolate themselves from humans. When they are seen, its usually entire armadas with dozens of BattleCon class ships and support, with the exceptions of a Nat or Lynx scout, and only when they want to be seen.)
