Just a little advice if you find yourself in this situation again:
Train MPK can be dealth with fairly easily, if you're prepared. First off, you need a bard, blm, or rdm/blm on MPK watch. Once you see the big train a coming, this person needs to disband, this is crutial. When the train arrives, your MPK controller casts horde lullaby/sleepga, and run the train back to where it came from. If it's a brd, hymnus is nice to have up, reraise for blm/whm, if you don't mind taking a big exp loss.
The reason behind disbanding is first off a healer might see your hp and heal you, getting hate. Second resting mages will get hate, and the train with come running back to you after it's done killing MPK controller.

Back to topic on maseki, one of the quotes struck me as so like maseki that I started laughing. I'd rather not dig through the thread to find it, but the one about bringing soo many people to camp a weak NM. Maseki, and some members of his ls, are the minimalist HNM hunters. They like to show up with as few people as possible to maximize their own profits. But hey, I'd rather take 18 people to bune and get the drop than take 4 and lose the claim. Oh no, I only get 500k if the sword drops that way. My thought is that so do 17 of my friends, not like that extra money is going nowhere or to some other random stranger.
Pretty damn cheap maseki, why would you MPK with weapons though? You definately need to take MPK 101. Weapons only sound aggro, and from the picture you weren't placing them in the ideal spot to aggro them. There's freaking undead there that aggro low hp from a huge range, that's what all the asshole serket MPK'ers use.
I lost respect for your maturity when you quit mo's god ls because you weren't allowed to lot on crimson boots abj (btw these are leaping boots +15hp/mp, not sure why he wanted them so badly)
I lost respect for your integrity when you stole ToD's from the lsmes on svina's shell.
And now you MPK another shell on serket cause they CC'ed you, congrats, you are now Lucifar in my eyes.
