Thunderbird of the Raging Storm

[Darklander]

Would one use the genitive gerund saeviendi for 'raging' when translating the following into Latin?

Thunderbird of the Raging Storm
Avis Tonitrus Saeviendi Tempesatatis

 

[Callaina]

No, you need a present participle.

Tonitrus avis saevientis tempestatis.

 

[Darklander]

Ah thanks for the clarification.
