Three doors into the same room.
A place, an article, a year. Erask gives you one way in for each — and once you are inside, every article you meet carries all three.
Radar
Centre the globe anywhere and sweep. Erask asks Wikidata what is notable within twenty kilometres and the places light up — a valley stops being a name and becomes a list of things that happened there.
Rabbit hole
Open any article and every place it mentions appears on the globe, grouped by the section it came from. Pick one and do it again. The trail fits inside a link.
Timed sync
Type a year — 1815, or 264 BC — and the whole world fills with what was happening in it. Nothing connects those events except the date. That turns out to be enough.
Each one holds a different thing still
That is the whole idea, and it is easier to see side by side. Every door fixes one dimension and leaves the other free:
| Door | Holds still | Leaves free |
|---|---|---|
| Radar | the place | every century that touched it |
| Timed sync | the year | the whole planet |
| Rabbit hole | the subject | wherever it leads |
Which is why they are not three features but one: the two that are incomplete complete each other. A place with no time is a pile of centuries in a heap. A year with no place is a list. Put one inside the other and you get the thing the map could never say on its own — Waterloo in 1815, and what else the world was doing while it happened.
Every article carries all three
This is the part that does not show in a screenshot. Wherever an article appears in Erask — in a radar sweep, in a trail, among the events of a year, in the card that opens when you touch a marker — it carries the same three small buttons:
◎ sweep the area around this place · ⌕ follow what this article names · ◷ see what else happened that year
So a trail is never a dead end. You are three hops into Napoleon, you land on Elba, and from that same row you can ask what else is on that island, or what the rest of the world was doing in 1814. The clock only appears when the article has a date of its own — a battle does, a mountain range does not, and Erask would rather show you nothing than invent a year.
And you can come back
Switching doors closes the previous one — two sets of markers on one globe are unreadable, and you cannot tell which belongs to what. But closing is not losing: a small line appears at the top, ← back to 1815, and it swaps rather than returns, so the way back is open in both directions.
Where to start
If you have a subject in mind, type it in the search bar at the bottom — a person, a war, a volcano. If you have a year, type that instead: Erask offers to take you there. And if you have neither, centre somewhere you are curious about and press Radar. That last one is the best way in, because it needs nothing from you except a place you already care about.
