Presumably they were attacked by some wild animals. We're the caverns open. There should be more detailed info than that in Legends.
Thanks
This fortress has no entrance to cavern and was some z-level deep..and all 17 dorfs were killed by other dorfs
Find out more...from the event log ( some filtering possible) on this : why the 17 dorfs are killed
Example:
0250-08-12 In 250, midautumn, (12th of Sandstone) Udil was taken by a fey mood in Walleddiamond. change hf state
0250-09-25 In 250, late autumn, (25th of Timber) Udil went berserk in Walleddiamond after failing to create an artifact. change hf state
0250-09-25 In 250, late autumn, (25th of Timber) Udil was struck down by the dwarf Ubbul Slingtaut the Diamond Virtue
with a (693) in (my fortress) Walleddiamond.
Now i know why Udil was strucked down by Ubbul : Udil became dangerous and maybe was Ubbul attacked by her?
With a (693) ?
Yeah, i can filter on date and event ( death), so the first died dwarf can be examined and 0n 250-09-25
In 250, late autumn, (25th of Timber) the dwarf Ber Moralmined was struck down by the dwarf Vutok Letterswallowed the Brass Brain of Teeth with a (578) in Walleddiamond
Vutok has killed more dorfs (5 on same date) and why ? and Ber had a normal mood
Vutok used as murder weapon: with a (578) ?
Vutok is a female and her goal was: create a great work of art
Vutok ..nothing to find about her mood
Vutok ..one day later she was killed by a another dorf Ubbul with a (693?) ( why?)
Could not find more ..maybe it was the stress level, because the dwarves became thirsty ( probably the drinksupply was not well done by me, unfortunaly still )
