The Book of Omens

Finally Panthr-O deciphers how to use the Key of Omens. He enters the code to open the lock and, suddenly, the Guardian of Omens is summoned and it tells the Thundercats they have 24 hours to present both the key and present four other items to the four places in disgrace (geological disasters) all over New Thundera. All was proceeding correctly except for the key, which was stolen by the evil Mumm-Ra. However, he enters the Book just when Lion-O found him and the battle will go on inside the book. This presented a somewhat legitimate finale for the complete series, with an open ending (which will continue in a short series of comics in an "after future" saga on the year 2002).
