Wormwood the blazing star is of course Constantine, as you well know. Constantine the great star made Christianity the official religion of Rome, but in his attempts to unify his empire, at the Council of Nicaea he enforced the theories of certain theologians upon the Christians in the form of creeds and dogmas and they have been taken to the very heart of Christianity to this day. The vibrancy of the church was destroyed forever.

Christianity which had been oppressed, then became the oppressor. These policies were continued by later emperors and led to a great schism. The Eastern Orthodox was one third of Christendom, another third formed the Western or Roman church and the last third was the Asian and African churches.

The bitter waters is false teachings and so no and so forth.

It speaks about the invasion of Rome by Visigoths under Alaric the Bold, the Vandals later, Huns, etc, the beginning of the Dark Ages in Europe. It resulted in a third part of the Christian hierarchy being separated from the mainstream church.

The church became darkened for a third of the day and a third of a night, this relates to about a 600 year part of a day of G.d, so that the Lord's day began with Jesus and ended about 600 years later with Muhammed.

Or it could mean something else altogether.
