Sounds like Star Wars episode 5. : This is a context question. Many things are ἀρθήσεται / ἀρθήσονται· either υπὸ τῶν νεφελῶν or ἐπὶ νεφελῶν. So I would have to say the meaning is the same as the other places ( Mt. 24.30 and 26.64 have the phrase ἐπὶ τῶν νεφελῶν. ) Then reading on in the passage even further to section 16.5, you find that the earth is wiped out clean (burned to smithers, becoming a virgin, all sin being gone), but the people are still alive (not destroyed)
[16.5] καὶ τότε θεωρήσει αὐτὸ ὁ τῆς ἀδικίας ἐργάτης μετὰ τῶν ὑπηρετῶν αὐτοῦ καὶ βρύξει μεγάλα, καὶ πάντα τὰ ἀκάθαρτα πνεύματα εἰς φυγὴν τραπήσονται. καὶ τότε ἀοράτῳ δυνάμει κρατούμενοι, μὴ ἔχοντες πόθεν φυγεῖν, βρύξουσιν κατ' αὐτοῦ τοὺς ὀδόντας αὐτῶν λέγοντες αὐτῷ· ποῦ ἔστιν ἡ δύναμίς σου; πῶς ἡμᾶς ἐπλάνησας; καὶ ἐξεφύγομεν καὶ ἐξεπέσαμεν ἐκ τῆς δόξης ἧς εἴχομεν παρὰ τοῦ ἐρχομένου κρῖναι ἡμᾶς καὶ πᾶσαν φύσιν ἀνθρωπίνην. οὐαὶ ἡμῖν, ὅτι ἐν τῷ σκότει τῷ ἐξωτέρῳ ἐξορίζει ἡμᾶς.
I found the hardest part of the sentence to be
πρὸς τὸν ὑπηρετούμενον παρὰ τοῦ διαβόλου ἤτοι τὸν ἀντίχριστον,
to the one being served by the devil, namely the antichrist or is it active
to the one serving alongside the devil, namely the antichrist? Anyways, that's my take.
taking ὑπηρετέω as passive 'the one being served'.
ἤτοι occurs infrequently. It means or and is often with ἠ...ἤτοι. Βut here ἤτοι = or = in other words τὸν ὑπηρετούμενον = τὸν ἀντίχριστον. Or am I wrong? cf. the quote below where it clearly has that meaning.

Morel page 427, section D, line 6 Πρὸ δὲ τῆς τῶν φωστήρων ποιή-
σεως ἡ κατὰ τὸν ὅρον τοῦ θεοῦ ἐπικράτεια φωτὸς ἐποίει τὴν
ἡμέραν καὶ ἡ ἐπικράτεια τοῦ σκότους τὸ σκότος ἤτοι τὴν νύκτα.
Γενομένων δὲ τῶν φωστήρων ἐτάχθησαν ἐξουσιάζειν, ὁ μὲν
τοῦ φωτὸς καὶ τῆς ἡμέρας, ἡ δὲ τοῦ σκότους καὶ τῆς νυκτός.
