Okay, so I got to the Forgotten Tomb (I did take the Elf Army with me), and I have NO CLUE WHATSOEVER as to what I'm doing. To be honest, I can't translate the words of the inscription that well. I got through, like, the first sentence then completely lost it. So if I could have help with that, the seals, and King Desius (what are those stat things he has under his health bar?), anything would be greatly appreciated. The party I currently use is Majesty, Silver Fairy, and Swift Swim.

The forgotten tomb boss is really hard to defeat, unless you've activated the seals. If you didn't, he would have more boosts during the boss battle, making it super hard to defeat.

Here's a thread discussing the forgotten tomb: https://www.sylestia.com/forums/?thread=622

The main thing is that you have to translate the text (I think there are some translations in the thread linked above), and match the right pet to the right skill needed. Your pets need a minimum amount of stat points in order to activate the seal. I heard most people use level 60 pets with all the points in that stat for it to work.

I can't remember much about the boss fight itself, so can't help you much there. The only thing I can advise would be to go to a lower zone and get your pets to full health and full mana just before you fight the boss, so you can use a finishing blow on him right from the start. Also, use mend whenever your pet's health falls below 75% if you can.
