Does anyone else think Tarquin is turning into Rich's Deus Ex Machina?
The plot just hit a point where 6 separate factions were approaching the gate for independent reasons (OotS, Linear Guild, Tarquin/Malack, mysterious Powers That Be, Xykon, Redcloak). In the middle of 4 conflicts (OotS vs X/R, LG vs T/M, OotS vs LG, PTB vs OotS), Tarquin returns backed by (what may be) the most powerful army we've seen and singlehandedly points the main characters back at the main plot.
Kinda like how when we first met Tarquin, the party was split and following a number of side plots. Tarquin then intentionally reunited the party and set them back on the main plot, even giving them the transportation they needed to do so (see comics 817-819).
I'm not complaining. A Deus Ex Machina is not necessarily a bad thing, and I'm enjoying the strip a lot right now. But it's worth noting this development for what it is.
