I bolded the words that should be changed in the underlined headings and put what it should read.
Edits for Chrono Cross Condensed Plot Summary
Settlement of El Nido (1 edit change)
"The Viper Clan was responsible for its founding, and probably
immigrated from mainland Zenan with others."
immigrated > emigratedSerge and the Frozen Flame (1 edit change)
"FATE took advantage of Wazuki's corruption, and
bega to shape him to FATE's will. Lastly, while the storm was down, the split Dragon Gods briefly came together to create a seventh piece, called Harle."
bega > beganChrono Cross Begins (1 edit change)
"She succeeded, and a new dimension was
fissioned off from the main one; the main is now called Another World, and the new one, in which Serge lives, is called Home World."
fissioned > "fissioned" (since it is not a real word...)
Schala's Freedom (1 edit change)
"Using a Time Egg, the same device by which Crono was
ressurrected in Chrono Trigger, Serge ventured to the Darkness Beyond Time, where the Time Devourer resided, and freed Schala."
ressurrected > resurrectedThe Lost Storyline? (2 edit changes)
"Signs point to another
overaching storyline that involved Serge binding with the Time Devourer itself;"
overaching > heart-wrenching"Chrono Cross Ultimania mainly supports this notion, claiming that the Arbiter of the Frozen Flame must mediate between his fellow
lifeforms and Lavos, or else he will inevitably bind with the creature and spell destruction for other humans."
lifeforms > life forms OR life-forms (editors discretion)
Serge's Perspective (3 edit changes)
"This information is later
expatiated by accompanied apparitions. Serge learns that the time research facility Chronopolis created El Nido thousands of years ago after a catastrophic experimental failure drew it to the past. The introduction of a temporally foreign object in history caused the planet to pull in a
counterbalnace from a different dimension."
expatiated > elaborated on (editors discretion)
counterbalnace > counterbalance"Thousands of years later, a panther demon attacked
a three-year old Serge."
The letter "a" is not needed here... (editors discretion of course)
