Before 21 BBY
|Chronological and political information|
Halka Four-Den was the commander of a Galactic Republic eight-member research team stationed on Dagobah before the Clone Wars. She kept an account of the exotic flora and fauna encountered on the distant planet, though much of it was lost. Among her discoveries were the unique knobby white spiders which later grew into the gnarltrees. Unfortunately, Halka Four-Den and her research team later disappeared on Dagobah before they could be retrieved.
