Glissa, Bosh, and Slobad journey deep within Mirrodin's core to confront the insidious Memnarch. With them is the Kaldra avatar—an immensely powerful being of energy summoned when Kaldra's sword, shield, and helm were brought together. But what was supposed to be the world's salvation turns out to be a vile trick. With a single spell, Memnarch seizes the avatar and turns it on Glissa and her companions. Kaldra's avatar relentlessly pursues Glissa into the Tangle, destroying everything in its way. Finally, at the Radix, Glissa's destiny becomes clear. As rage and despair overcome her, Glissa's body calls forth a great column of green mana from Mirrodin's core, annihilating the avatar in the process. Now that mana hangs overhead in a glowing sphere—the green sun at last, Mirrodin's fifth dawn. Set history Mirrodin Mirrodin is notable for being the first expansion set to feature the new card front design (which debuted in 8th Edition). The high number of artifacts in Mirrodin highlighted the inherent flaw of the new border design — artifact cards, which were now bordered in a very light grey instead of brown, were very hard to distinguish from white cards. The problem prompted Wizards of the Coast to change the bordering background of artifact cards to a much darker grey in Fifth Dawn. Also due to complications when switching to the new card frame, mana symbols in the text box of Mirrodin cards are greyed out instead of being in color. Beginning with Mirrodin Wizards reduced the size of their large expansion sets from 350 to 306 cards. This was due to regular complaints, that Wizards was producing too many cards and players could not keep up. Beginning with Darksteel Wizards also increased the size of small expansion sets from 143 to 165 cards. Thus the number of cards released each year would stay the same, but then Magic developer Randy Buehler explained that Wizards believed this change would make it easier for collectors and players to keep up with the number of new cards as these would be released more homogeneously over the course of the year. Darksteel Darksteel was the first "small" expansion to have 165 cards, whereas previous small expansions had 143, (with the exception of Legions which had 145 as a balance among the five colors.)
