moriturus, -a, -um

In LLPSI Cap XL Orberg has Dido say to the soon-to-depart Aeneas:
Ergo nec noster amor nec dextra [promissum] data te tenet nec Dido crudeliter moritura?

Is moritura simply an adjective meaning about to die ? I made a note earlier that it was a fut. participle…but I don’t think it is… Am I missing something..?

…if it is a fut. participle…what verb is it a fut. part of…because 501 Latin verbs doesn’t give it as a fut. part of morior, mori and Whittakers Words gives it as a fut part of :

-, -, moritus sum V DEP ?.. i.e. a verb with only a perf. passive. participle..!!!

It’s the future active participle of the deponent verb morior.
