A couple of thoughts. If you want the players to go back, or consider going back, to the druegar after/if they escape. If they go to the dwarves. Then then dwarves (via a quest or a sage or xxx) could inform them that the they know where they can get corals. One place is a cave now inhabited by a bunch of druegar... (ha! forces them to go back) or their is a hidden grove up in the mountains, but the grove is considered a meditation place for the giants (hence why the giants are stationary). Maybe they can get in and out without disturbing the giants, who would get upset at being disturbed, and maybe they can't...
You can keep these ideas simple and fast, or you can put twists and turns and prerequisites along the way to make it more detailed and lengthy. I suggest you research "three clue rule" and/or "node based scenario design". Several folks, including Justin Alexander, cover the topics and they can be very useful for designing a sandbox or non-linear adventures.
Why am I now remembering TrollBall? An old game within a game from Runequest; you run a sports team made up of trolls, and they use goblins/kobolds as their ball. You lose points if you kill the ball...Now to decide what that place is, if it's not a meditation place.......
Do you see the giants are intelligent or belligerent? Are they involved in some intellectual thing and being interrupted by the party is offensive to them? Or is it just that they are angry and selfish and will attack or try to eat anything that comes there way? Are they Evil? Chaotic?
Kind of like the treant from Lord of the Rings? Time may not be something they particularly worry about, since they might (?) live for centuries. Or at least time for them is on a different scale than for short lived humans and the races that they influence (elfs, dwarves, etc).
A comparison might be like I am when sitting on my back porch with a drink; the gnats and other bugs scurrying about my feet I don't notice, until I do. Then I might just squish them flat because they dared climb on my foot. Or land on the table I'm about to put my drink on.
maybe they see us like spiders?This is very fitting!
Only one question remains: what prompts the giant to wish to squish those pesky humans flat?
maybe they see us like spiders?
Only the truely Evil squish spiders with no reason,maybe they see us like spiders?
I agree with you my mother not so much.Only the truely Evil squish spiders with no reason,
so stoic lawful evil giants squishing humanoids is it?
