As ruler of Legerdomain, Charmcaster says the door is hers and as such she can change the true name of Ledgerdomain whenever she wants making it almost impossible for anybody but her to open it. Gwen described what Charmcaster did as the magical equivalent of changing the door's locks.
Charmcaster put an enchantment on the door so the true name of Legerdomain changes every few seconds. However, Gwen stole a spellbook from Hex that kept a record of whatever the true name of Ledgerdomain was at that moment. Using the spellbook and a prediction decryptive algorithm she made on her laptop Gwen was able to know what the true name of Legerdomain was going to be when it'd change again.
By speaking the true name of the place to which the person wants to go, they can step through the door and be magically transported there. The door can be summoned by the use of a gateway spell in Gwen's Spellbook.
In Enemy of My Frenemy, Gwen, Kevin, and Ben traveled to Ledgerdomain via the Door to Anywhere to rescue Charmcaster from Adwaita only to discover Charmcaster as the new ruler of Ledgerdomain.
In Couple's Retreat, Darkstar stole Gwen's Spellbook and used it to summon the Door to Anywhere in an attempt to enter Ledgerdomain. However, he fails in getting the door open, but Charmcaster decides to let him in anyway in an attempt to relieve herself of the boredom she's endured since she took over Legerdomain. After Darkstar's good looks return to him as his body absorbs the mana in Ledgerdomain, Charmcaster becomes spellbound with him and for a short while Charmcaster and Darkstar teamed up to destroy Ben, Gwen, and Kevin. However, Charmcaster later threw Darkstar out of Ledgerdomain and changed the name of Ledgerdomain again so he couldn't come back after she realized Darkstar didn't love her; he just loved the power that she gave him.
- The Door to Anywhere is similar to Anyway Door from the Doraemon Franchise.
