The future tense adds the suffix -e. It also follows the consonant-cluster rule of the past tense. Example: miable, I will have.
If you have studied German, this is what you would consider the spoken past, if not, it is when one says, "I have left." Not "I left" but "I have left." In Diarenyë, as you will no doubt recall, the verb "to be" can be either "esar" or "vetar." Until now, you have not had much occasion to use the "vetar" form. This is where it is used. Example: Mivetar mazarai. I am finished [done.] The verb "ablar" is also used. Miablar yesarai. I have gone. It can also be used in the future. For instance, "I will have eaten lunch by the time you return" uses a future past perfect.
You will notice that everything is getting shorter, explanations, instructions, etc. This is because you are reaching the point in Diarenyë where you can understand the grammar much more easily. In the beginning, you were starting from scratch, by now you will know many words, phrases, and grammatical terms that will help you in your study.
