Do note this and the 3rd book are part of an omnibus edition "mistakenly" identified on Amazon as singly book 1. This particular book within the omnibus edition, Campaign, is an enjoyable read.

Everyone gains in power, even within the "Instance" though through a bit of wheeling and dealing with the Scouts by Sebastian, largely to save the life of Aleron. Everyone shows off a bit in the "dungeon raiding" they are forced into. Well, perhaps not initially Mercy or traditionally at all so Sebastian. And they end up bankrolling a large sum the "Scouts" are unaware of as well as some killer gear. It is suggested at some point that the Scouts are actually time travelers. Not sure how that actually fits into this book or even makes any actual sense since they would have had nothing to travel into until approximately the time the beta testers entered the game. Frankly, the notion of traditional and even otherwise time travel came off as really cheesy to say the least. I do hope it is sort of metaphorical or is revealed to be in some other fashion. To say it is so traditionally or such would be pretty WEAK!! Anyway, it does not deter me as I am well into book 3 now already and laughing at Isaac's attempts to contact Sebastian and the means and "personae" by which he thinks it best to do so. What a dumbass!!
