One thing I have noticed about the titan is it is heavily destruction based. So I have an idea for another titan.
Dragon lord Serra (name random)
info: this dragon desends on towns who make a name for themselves in wealth and trade. She can not be beaten through pure strength of muscle but must be appeased to make her leave.
Calling the titan: town is gifted an empty basket and told to fill it with gold if you do. you call in the dragon for this fight.
Titan health: goes down if you make their crafting, and trade requests as well as wealth requests and food requests. This one is purely a crafting fight.
type of titan events.
hungry welps: The dragon requests that you have X meat based food by Y days when those days arrive a kobold will enter the town and take the supplies before leaving thanking you.
The horde must grow: gain X gold in Y days
Crops for the kobolds: The kobolds are requesting food, will you give it to them?
Shiny things: give ore or bars of metal to the dragon
building up the lair: produce a high quality item nomrally stone based lights or turrets.
This titan can have multipul requests at once, failing to apease it will lead into combat with welps which are smaller and can light hearthlings on fire, beating them will give half what the reward was for completeling the task.
When the event ends, the titan will leave, but not before giving your town a gift a single dragon egg.
I know the current titan is meant to avoid the, town destroyed by dragon trope, but this one is a less destructive one not out to destroy the town but to get what it can from the town, with some of its objectives being being trades like you give it gold bars it gives you cloths or tools.
Reward: dragon egg
info: can be placed like any other item, once placed and if it has enough heat (lights around it) it will hatch into a welp that will protect the town and produce scales which can be sold for a high price.
