As mentionned yesterday in our news, the latest edition of a Russian magazine called Game Land includes some details about the towns and creatures of Heroes V. Some of the information has been posted by Sarsis on the official forums. Here are the names of the Sylvan and Academy creatures, ordered by level:

• Sylvan: Spirit, War Dancer, High Elf, Battle Unicorn, Dendroid Soldier, High Druid and Gold Dragon.
  
• Academy: Master Gremlin, Obsidian Gargoyle, Golem, Mage, Master Genie, Rakshassa, Titan.

If some scans aren't made available on the Internet, we should get more information about these two towns on the official site someday.
