So, the events surrounding the party's involvement with the Unseelie and Seelie courts have reached a pay-off. Due to the party's failure to deliver the McGuffin to the Unseelie Princess, they took it upon themselves mount a rescue mission to save their friend.
They enlisted the help of the Seelie, prior to their decent into Niflheim, to try to locate the captive for a potential rescue. The Seelie were able to determine approximately where the Unseelie's agents were holding the kidnapped victim (on Vanaheim's Shadow Plane). After all the PC's were resurrected, they contacted the Seelie once again, and were asked if they "knew how to travel the tree." There was some confusion about that (they thought I meant Transport via Plants), but after I explained, they traveled to Yggdrasil, Shadow Walked to the shadow plane, and entered the tree. About 45 minutes of step-climbing brought them to a landing where an elfish-looking male stood. He introduced himself as Kimball, and he was a Saint Ghaele Eladrin (ie - a Seelie courtier). He accompanied them through the adventure, and pointed out the ability to use the time flow traits of Vanaheim to their advantage (they retreated to Yggdrasil several times to reprep spells a total of two times).
He assisted the party, and after all was said and done, and the Shadow Creature Master of the Hunt was slain, he told the PC's to come visit his princess at the next full moon (via the fey ruins and the seat that allows someone on Midgard to see through the veil into Vanaheim).
The PC's spent the next two months in game recreating spellbooks, selling the Hunter's Large items to the Troll King, and crafting new items. Along the way, at the next full moon the Wizard//Rogue and the Barb//Beguiler went to the fey ruins, and Barb//Beguiler sat on the stone bench and conversed with Tatiana. He asked for advice and ways to protect against Unseelie retaliation, and Tatiana said she could do two things. One, she would send Kimball to teach them things (I have to figure out WHAT he will teach them, exactly... hmmm), and two, after Kimball's report on their actions to save their friend, she could "bless" them, and make them agents of the Seelie.
I then broke out of character and explained what her blessing entailed. She could bestow the Saint template upon any of them that were of Good alignment. I explained how the LA would work (in my gestalt games, the LA is split between both sides; as a +2 LA template, it would effectively take up their next level, +1 LA on each "side,") and the benefits the template would bestow. The player of the Druid//Sorcerer... his eyes kept getting larger and larger. Though his character wasn't present at the time, he was giggling and saying "yes" before I was half-way through reading the template. He is currently CN, so I am forcing him to roleplay his change, first the true neutral, then to neutral good, over the course of a few sessions. Then Tatiana will bestow it upon him during a full moon.
The Good Wizard//Rogue is debating whether or not to take it. The CN Barbarian/Duskblade//Beguiler/Mindbender with Mindsight is actually quite bummed, because Mindbender (and thus Mindsight) require him to be non-good. He can, of course, choose to become a "better man," if the Saint Template is more enticing, but he is quite conflicted, and it seems to be a very hard decision for him.
In talking with the Barb//Beguiler player after the game, I mentioned the effect events in game have had. Not to rub his face in anything, but just an observation. Had they succeeded in returning from Niflheim with the Hammer of Thunderbolts, the Unseelie princess might have seen them as powerful enough to become agents for the Unseelie Court, and would have offered the Shadow Creature template. Due to the outcome of events, that option is pretty well shut down, but I've been intending for one of the archways in the fey ruins to periodically function as the Failed Shadow Gate magical location from Cormyr: The Tearing of the Weave, which can bestow the Dark Creature template (but only for 10 minutes, 1/day; the book says many of the foes passed through it more than 10 times, however, permanently becoming Dark Creatures).
I've not yet decided how, but I plan to make that option known at some point.
