Description
10岁,他的家乡因战争而被毁于一旦,他被迫逃亡。逃跑途中,他不慎摔入一处因爆炸而出现的缺口,在那里,他见到了沉睡已久的锁与匙。
20岁,他成为了一名术师,凭借着锁与匙赋予他的力量,他以极快的速度开始获得赏识。
30岁,他获得了曾经梦寐以求的财富与名声,但此时的他却早已对这一切不屑一顾。不知从什么时候开始,他日复一日地与手中的杖对话,所有人都以为他已经疯了。
40岁,有一天,他忽然消失在了宫廷中,没有人知道他的去向。卡兹戴尔一些地区开始出现一个传闻,据说有一个疯子,他会在荒野上向路过的人预言一些不可能发生的事,例如巨大的兽将毁灭我们的国度,天空有一天会裂开,向人展示它真正的面貌。然后,他会向他们兜售钟表,如果对方不买,他就会停止对方的时间。
到他百岁之时,他已经不知道自己身处何地,但这于他已经失去意义,他相信自己在探寻时间的秘密。
他有钥匙,可是锁在哪里?
他有锁,可是钥匙又在哪里?
过去成为未来,未来没有秘密可言,他日复一日地和自己的影子对话,坚信一切的真理蕴含其中。
直到有一天,脚步声响起,三个萨科塔走入地宫——
