Which is a contradiction as official artwork released by SE actually shows our old friend Derplander in Haukke Manor fighting succubi with his friends.

Then there is plenty of other art showing multiple party members in other boss battles, raids and dungeons: fighting the Behemoth FATE, fighting Leviathan on the Whorleater, the Final Coil of Bahamut, even Ifrit has artwork depicting multiple fighters at his summoning (although, it is stylized, and how many have the Echo there and are thus not tempered immediately is a good question. ).

So, I'm liable to take what the lorebook says that those fights at least were only fought 'canonically' solo with a grain of salt.
