The Dragon Rider
The most notable report about the
dragon is that there was a rider
on its back. Besides a few lesser
monsters, such as Coolias,
no creatures exhibit fond
behavior towards humans.
The identity of this rider remains
a mystery, but his amazing
reactions and advanced combat
skills indicate he’s not human.
Thus the Academy has theorized
that he is a human-shaped
creation, similar to the monsters.
The Dragon and the ‘Tower’
According to the ancient records,
the dragon and the final weapon,
the ‘Tower’, are linked somehow.
Our researchers are split between
the theories that the dragon is
the Guardian of the Tower or that
it is the destroyer of the Tower.
On Imperial Year 89, while the
Empire attempted to reactivate a
Tower, two dragons appeared, and
acted in completely opposite
manners. This created even more
confusion over the dragons. All we
can conclude is insufficient data.
From the Dragon Report, though I almost think I remember something else along those lines, but I can’t recall where it might be. Possibly even from Orta’s Encyclopedia. Regardless, most of these texts are presented as Imperial research speculation, and can be intentionally contradictory. The form even appears to carry over to the Encyclopedia. About the only info that could perhaps be considered empirical (in canon terms) is from the enemy descriptions in Saga, as they don’t usually appear to have any bias or ambiguity. As far as in-game material at least.
And I think the Heresy Dragon is much like any other dragon, designed to be “incomplete” as a combat unit without it’s rider. So again, while I have personally adopted the Divine Visitor into the way I see things, the basic premise still works either way. Perhaps if the Dark Dragon had any way of knowing the Blue Dragon could just pick up a random human as a replacement rider? It adds a whole new subtext to that inspection it gives you at the end of Act 2, like… getting owned by mangy human, does not compute! lol
Which is actually another explanation I’ve considered for the no berserk question. That there just wasn’t a strong enough bond between the dragon and Keil/Kyle yet. Or even possibly that it’s a different body than Lagi’s original form, of course that gets even more complicated.
