The past tense of "rend" is "rent." Once you've applied rend, it's been rent.

[Shurrikhan]

Adding -ed isn't the only morphological inflection possible for the past tense. Vowel shifts and voiced to voiceless, or unaspirated to aspirated, ending consonants (e.g. -d to -t) are also used.

And I'm sure the dialogue here and there in the English client will also show off the fact that such inflectional choices were less standardized in the past. (In fact, there were more -ed endings available back then, but as one of multiple options—just as more 'strong verb' inflections remained back then as well.)
